2D Polynomial Geometric Transformation
An images.geotrans.PolynomialTransformation2D
object
encapsulates a 2D polynomial geometric transformation.
tform = images.geotrans.PolynomialTransformation2D(movingPoints,fixedPoints,degree)
creates
an images.geotrans.PolynomialTransformation2D
object
given mby2 matrices movingPoints
,
and fixedPoints
which define matched control points
in the moving and fixed images, respectively. Degree
is
a scalar with value 2, 3, or 4 that specifies the degree of the polynomial
that is fit to the control points.
tform = images.geotrans.PolynomialTransformation2D(A,B)
creates
an images.geotrans.PolynomialTransformation2D
object
given polynomial coefficient vectors A
and B
. A
is
a vector of polynomial coefficients of length N that
is used to determine U in the inverse transformation. B
is
a vector of polynomial coefficients of length N that
is used to determine V in the inverse transformation.
For polynomials of degree 2, 3, and 4, N is 6,
10, and 15, respectively.

Dimensionality of geometric transformation Describes the dimensionality of the geometric transformation for both input and output points.
